TheZener equation wasfirst reported by C, S. Smith in 1948 and since then it has becomean
integral part of any theory which deals with recovery, recrystallization and grain growth in …

This paper reviews progress made in understanding the factors which control the
supersolidus liquid phase sintering of high speed steel powders to full density. The …

Mixtures of AISI M2 high speed steel and vanadium carbide (3, 6 or 10 wt.%) were prepared
by powder metallurgy and sintered by concentrated solar energy (CSE). Two different …

High speed steel powders (T42 grade) have been uniaxially cold-pressed and subsequently
densified through different sintering routes including: supersolidus liquid phase sintering …

Metal injection moulding (MIM) was used to process steel matrix composites reinforced with
different amounts of vanadium carbide (VC) for tooling applications. The effects of adding …

The mechanism of grain growth stagnation by second-phase particles or pores, also known
as Zener pinning, has been analyzed through a variety of theoretical approaches. These …

The sintering behavior of T15 and M2 water-atomized high-speed steel powders under
vacuum and N 2-H 2-CH 4 atmosphere is analyzed. Sintering under the gas mixture allows …

The steel powders were sintered under N 2–H 2 atmosphere in a solar furnace and in a
Fresnel lens, after compaction of the green parts, using much higher heating and/or cooling …

A novel concept for full-density sintering is described. Two prealloyed powders with slight
compositional differences are tailored to separate the solidus temperatures into high-melt …

A novel technology which was characterized by the vacuum solid state sintering was
developed for powder metallurgy high speed steels production. During sintering, both the …
